How is diffusion different from osmosis?
The essential idea is the same: diffusion is the process by which molecules spread from areas of high concentratiion, to areas of low concentration. Osmosis is the process by which molecules of WATER spread from areas of high concentration (such as a dilute solution) to areas of low concentration (such as a concentrated solution), typically through a selectively permeable membrane. In short: Diffusion occurs as is, while osmosis occurs through a semi permeable membrane.
What occurs in a hypertonic solution?
Water diffuses out of the cell, and the cytoplasm shrinks and gets more concentrated .
How does osmosis take up water?
Osmosis is the transfer of a solvent (e.g. water) through a semipermeable membrane from a less concentrated solution on one side to a more concentrated solution on the other side. Osmosis is driven by ordinary statistical diffusion, the same movement of solvent occurs even without the membrane but the membrane prevents other types of mixing (e.g. mechanical, convection) that would allow mixing of solutes in the solutions. Only mixing by diffusion through the membrane is allowed.
What occurs when diffusion has occured and molecules are spread out evenly in all directions?
A homogeneous solution is formed when diffusion has occurred and molecules are spread out evenly in all directions. It has uniform composition and properties throughout the solution.
What is called the diffusion of water?
OsmosisOsmosis is not the same as diffusion of water. Diffusion of water is just diffusion like with any other substance: the particles spreading, making a homogeneous distribution. Osmosis involves a semipermeabel membrane, where water goes from low solvent concentration to high solvent concentration.osmosis
Why diffusion is important for living thing?
Diffusion is the movement of molecules from an area where they are more concentrated to an area where they are less concentrated. In other words, diffusion occurs when concentrated molecules spread out and become more randomly distributed. Diffusion is important for all living things because it helps cells get materials they need, and get rid of wastes they don't need. If food is concentrated outside of cells, it can diffuse into cells. Water also diffuses in and out of cells depending upon the concentration of other molecules in the environment. The diffusion of ions is essentially for the proper functioning of nerve and muscle cells. Your body also relies upon diffusion to move oxygen from your lungs into your tissues, and in the processing of wastes in your kidneys. Basically, all living things rely upon the process of diffusion to move molecules from one place to another.
Where diffusion occur?
Diffusion occurs on the cell membrane.

What is the processes of diffusion and osmosis?
Osmosis is the movement of water from a less concentrated solution to a more concentrated solution through a partially permeable membrane. For osmosis to happen you need: * two solutions with different concentrations * a partially permeable membrane to separate them Diffusion occurs when particles spread. They move from a region where they are in high concentration to a region where they are in low concentration. Diffusion happens when the particles are free to move. This is true in gases and for particles dissolved in solutions. Particles diffuse down a concentration gradient, from an area of high concentration to an area of low concentration.

Why does diffusion occurs?
To reach an equilibrium of concentrated solute particle. It's the process by which particles move from an area of high concentration to an area of low concentration. A simple reason why this occurs is that particles are always bouncing off each other, and an area with a high concentration of particles would be harder for a particle to bounce into than one with very few particles.
What happens throughout a liquid and not just at the surface?
Diffusion occurs throughout the solution and not just at the surface. Just the opposite of this is the activity of enzymes. Dropping colored dye in water will diffuse evenly through the solution.
Does diffusion occur in the digestive system?
Diffusion occurs when something something something
